HXGN-12 High voltage ring network cabinet
HXGN-12 series switch cabinet is suitable for use in ring network or terminal power supply system of 3.6-12KV、AC 50HZ, as an indoor complete distribution equipment to accept and distribute power, it is also suitable for substations.
Main characteristics:
1.The load switch is independent, internal filling with sulfur hexafluoride gas as insulating medium, long life, highly configured, pollution-free, less maintenance.
2. The cabinet shell is made of high quality aluminum zinc plate, with characteristics of anti-corrosion, anti- oxidation, and novel appearance.
3. Spring energy storage operation, three-phase automatic tripping, integrated “five- prevents” interlocking and operating mechanism, safe and reliable linkage
4. Ring network cabinet can easily constitute ring network power supply units and other connection modes, with good expansibility.
5. Adopting sulfur hexafluoride load switch, with safe and reliable performance, no oil, non-toxic, no fire and explosion danger
